i have a buddy who was the tour manager for the go-gos. they were in the studio and apparently metallica was too. they got to talking to the engineer. he said that lars' parts (this was back in the 90s) were all spliced up . . . they had to really splice up the tape to make the parts good. and not just spliced a little bit. A LOT!

Bob Rock says on the Classic Albums DVD of the black album that they did ALL the fills seperately from the rest of the drum parts. He also says they had to change the heads after every 5 takes or so, because Lars destroyed them after that long. Then he compares him to John Bonham or Keith Moon. Strange man.
